【Abstract】 Deducing a general expressions by comparing and analyzing the Mohr?Coulomb yield criterion and von Mises yield criterion. Based on the condition that the area of equivalent circle equal to the area of Mohr?Coulomb yield criterion, then Lode angle of the equivalent circle is obtained, so the Mohr?Coulomb yield criterion and von Mises yield criterion achieve to unify, which makes easy program. The functional expressions relative to the equivalent area circle and every D?P criterion provide a transformation between each other, which make calculation simpler. The results show the method mentioned above is feasible.更多还原
